A reconstruction of a manuscript which was subsequently re-used as flyleaves in a number of Worcester manuscripts, and now survives as a set of fragments, mostly polyphonic, in several different collections. Fragments from the collections Worcester Add. 68, Bodleian MS. Lat. liturg. d. 20 and British Library Add. MS 25031 - qqv. - form parts of this reconstruction.

The original ms may have had 140 or more folios; fragments remain of 30 or more. The original position of several of the fragments (notably those collected as Add. 68 fr. xiii & xl) cannot be determined. It was probably broken up in the 1520s; fragments have been recovered from volumes bound c. 1527-31, most surviving in Worcester Cathedral.
